Specification of Letters Patent.

Patented. June 12, 1906.

Application filed November 18, 1903. Serial No. 181.655.

T (LZ/"ll whom, zit 172,@ 1/ concern: v -Be it known that I,'EUGENE J.LoeAN, a citizen of the United States, residing at`Baltimore, the State of Maryland, have in-v vented certain new and useful Improvements' in Machinesifor Cutting Tubular Bodies, of which the following is a specification.

The purpose of my invention is to provide a machine for cutting off the ends of tubular bodies, and vthe machine made according to my invention is designed particularly for the purpose of cutting off the ends of tinl cans such as are largely employed for containing and preservin foodstuffs. At present when the contents o these cans have been removed by cutting open' their heads the cans are thrown away as worthless. With my'inachine I am enabled to cut olf the ends or heads of these cans very rapidly, soA that the body portions may be preserved, and after being cut open longitudinally and flattened these body portions' are converted into flat rectan- `g'ular pieces of sheet metal, for-which there lis a large demand in the manufacture of small articles. By means of my invention a very large amount of material which now goes to waste may be saved. While the invention is particularly adaptedfor this purpose, it may be used for trimming or cutting oil the ends lof tubular bodies of anydescription.' Y

Fig. 5 is a side view ofthe ratchetmechanism for --operating the feed-wheel looking from the left in Fig. 1, the pawl being shown at the limit of its upward movement with the locking-pin .which locks the feed-wheel lifted b'y the cam-surface of the pawl. Fig. 6 is a view: ofA the same-parts looking from the right in Fig. 1, but showing the pawl started on its downward movement and the locking-pin restin T upon the curved surface of the detent-whee Fig. 7 is a cenjtral vertical section through the worm-wheel and clutch mechanism by which the machine is connected to the driving power, and Fig. 8 is a section'on the line 8 S of Fig. 7.

Referring to the drawings, A indicates the supporting-frame of the me. chine, at the rear end of which is mounted. a driving-shaft 1, carrying fast and loose pulleys 2 and 3, to which the ordinary shifting-belt from any suitable source of power is in practice applied for the purpose of operating the niachine.

Upon a shaft 4,.arranged parallel with. the driving-shaft and at about the longitudinal center of the supporting-frame, is a feedwheel 7, carrying on its periphery a series of clamps or holders 8, each adapted to holdv ari ordinary tin can Jrmly whenthe movable jaw 8a. of. the clamp is pressed towardthe iixed jaw 8b. For the purpose'of gripping the can-body firmly without excessive pressure the semicircular faces of these jaws are I preferably lined with rubberr or some other suitable material 'which will prevent the can from turning -in the clamp. This feed-wheel extends upward through a slot 9 in the top or bed 10 of the supporting-table and carries the clamps between a pair of circular saws 11, which operate in the mannerhereinafter described to sever the ends of the cans from their body portions. The clamps a're not quite equal in width to the length of the cans y C, so that the ends of the cans project at each cured to the shaft 4, (see Figs. 2, 5, and 6,) anda pawl 13,' engaging said ratchet-wheel and operated by means of a cam 14 upon a .tently bylmeans of a ratchet-wheel 12, se-

shaft 15, which is arranged transverselyof the machine. The'pawl 13 is secured to an arm 13a, journaled upon the shaft 4, and the outer end of said armis connected by a link 13b to a strap 13, encircling the cam 14. This shaft 15 is geared to a shaft 16, similarly located'and arranged at the opposite side of the feed-wheel by means of sprocket-wheels 17 and 18 of equal diameter, secured to said i IOO shafts respectively and connected by a sprocket-'chain 19. These shafts are revolved fin' unison by means of a worm-wheel 20, secured to the shaft 16 and engaged by a worm 21' upo'n the main shaft 1. The pawl 13 makes one downward and one upward moveinent for each revolution of the shaft 15, In the drawings eight clamps are shown connected to the periphery of the feed-wheel, and

the movement of the pawl is so proportioned that at each downward movement it will ro`- tate the feed-wheel one-eighth of a revolution,

1 and thus bling the clamps in succession to i the saws at the top of the machine.

During thegu ward movement of the pawl the .feed- -Whe 'remains stationary with one of its clamps in position for the saws to. operate upon-the can held within the clamp. If a smaller or greater number of clamps are used,

cut off, a detent-wheel 22, Figs. 1 and`6, is

arranged upon the shaft 4, and this detentwheel is provided with eight equidistant slots 23 in its periphery, which'are engaged successively by a spring locking-pin 24, mounted upon a fixed part of the fram'e. Thislockingpin is held out of engagement with the detentwheel durin'g the downward movement ofthe.

pawl and engages one of the slots in said wheel after the pawl has completed its downward movement and during the upward .movement of the pawl. This is accomplished by means of a cam-'surface 25 upon the pawl,

which engages a-projection 26 upon the locking-pin and lifts the latter out of engagement with the detent-wheel just before the pawl reaches the limit of its upward movement. This cam-surface holds the lockingpinin its disengaged position until the pawl again starts downward, and as" the downward movement of the pawl causes the detent-wheel to turn with the ratchet-wheel and feed-wheels, the slot which the lockingpin had just been lifted out of will move downward out of alinement with the pin before the latter is released from the cam-surface 25. As soon as the pin is released it drops upon one of the arcs 27 of thc periphery of the detent-wheel between adjacent slots 23, as shown in Fig. 6, and rides upon this are until the pawl completes Aits downward movement, when the pin drops into the next slot which is brought into alinement with the pin, and the feed-wheel shaft therefore becomes locked in position until thcpawl again" approaches the limit of its upward movement.

The saws are given a rapid continuouscircular movement and an lntermittent orbital movement concentric with the axis of the adjacent clamp in order to sever the heads from the cans. Both saws are similarly mounted and operated by similar trains Aof gearing mounted upon supports on `the bedy of the machine, the two saws and their'ge'aring being .arranged at opposite sides ofthe feed-wheel. f

A description of one setof gear there- 7o` fore apply to both. As shownin i'gl 1 of the drawings, each saw is secured tolan arbor or saw-shaft 28, j ournaled'in ahead 29, forming mounted upon the bed of the machine, and

collars 33 and 34, securedlto said sleeve at the ends of the bearing. This sleeve is rotated intermittently, as will be ,hereinafter de- `8o scribed, to give the sawzits .orbitalymovement. AA shaft 35 extends lon itudinally` through the sleeve-and is journaedvtherein and also Within a bearing in a standardl at the and naaimachine-frame. 'rhisfshaafa-sisss geared to the saw-shaft 28 by means ofva gear 37 upon the shaft and a' pinion38fponthe 1 saw-shaft,'this gear and pinion bem arranged'within a recess 39 in the hea `29.`

The shaft 35 is driven bymeans' of a gear 40 9o upon said shaft, meshing with agear 41u on la counter-shaft 42, which is journals in standards 36 and48 upon the bed of themachine and driven by a sprocket-chain .44,

.passing'around a sprocket-wheel 45 upon-the 95 shaft 42 and a sprocket-wheel 46 upon fthe main shaft 1. This arrangement-pf gearing gives each sawa rapid circular movement, and as the feed-wheel carries a can to the saws the latter cut into the can-body vat the rear and near the top ofthe can, as indicated in Fig. 2E. The normal positions ofthe saws are shown in Fig. 1 andtheir direction of ro-- tation is indicated by an arrow a in Fig. 2a. As soon as acan is broughtinto position and the feed-wheel lockedl against movement by the locking-pin 24 thes'aws commence thelr orbital movement in the -direction indicated by the arrow b in Figs. 2'and 2a. As the saws travel around the can-body it will be seen that the teeth of each`saw will cut circumferentially around the can-body from the interior outwardly, and as there is very little clearance-space between the saws and the adjacent ends'of the clamp advantage is taken of the shearing action between the saws and the edges of the clamps. By reason of this the cutting work of the saws 1s more effective than if the saws revolvedin the opposite direction, in which case the teeth would cut from the outer surface of the can inward. 'This orbital movement of each saw is accomplished by the rotation of the saw-carrier B, by which it is carried and which is automatioallystarted when a can is 'brought into position for cutting and which is automatically stopped after the saw-carrier has made a-complete revolution, so that the saws will,

roo

IIO

be held in proper position to engage the sucis extended beyondv the collar 34 and is engaged by a pinion 48 upon the constantlydriven counter-shaft 42. The collar 34 is sep cured to the sleeve 31, and this collar, which Jforms a clutch-head for connectingthe sawcarrier to the loose gear 47, is provided with a spring-pin 49, adapted to engage a socket 49a in the adjacent face ofthe loose gear47. The collar or clutch-head. 34 has a peripheral groove 49h, and the pin 49, Fig. 1a, extends transversely across this groove and has in its side a recess 50, forming a shoulder51,which when the pinis in engagement with the gear is at one side of the center of the peripheral groove. This pin is normally disengaged from the socket in the gear-wheel b a shoe or cam 52, having a beveled forwar end 53. (See Fig. 3.) This cam is mounted upon a lever`54, which is intermittently moved to raise and lower the camv within the groove. When the lever 54 is raised, the spring-pin is released-and engages one of the notches in the -body which is held stationary gear-wheel 47 and the 'saw-carrier makes one revolution, the saw passing around the canin the clamp and severing the head. After the carrier has made one revolution the pin in the clutchhead is withdrawn from engagement with the loose gear 47 by the enga ement of the camsurface 53 with the shoul er' 51 the cam hav- -ng been lowered into the bottom of the groove 49b during the revolution of the sawcarrier for that purpose. To insure the stoppage of the saw-carrier at the same point after cach revolution and to lock it in this posi tion,-

a locking-lever 55 is raised and lowered simultaneously with the movement of the am-,

-lever 54, and this locking-lever carries a pin 56, which engages a notch 57 in the collar 33,

which is secured to the sleeve as soon as the locking-pin in the clutch-head is Withdrawn from the loose gear. The Vsleeve is therefore prevented. from ,turning until both thecam-lever 54 .and locking-lever 55 are raised.

As shown, the levers 54 and 55 are each similarly mounted upon pivot-pins'59 in brackets 60, extending upwardly from the sleeve-bearing 31, and the adjacent ends of` said levers'overlap and each is provided with a slot 61, these slots registering with 'one .'another. A spring 62, arranged between the ladjacent ends ofthe levers and the top ofthe bearing 31, presses upwardly upon said adjacent ends yand forces the cam on the lever 54'and the locking-pin onthe lever 55 downwardly against their engaging parts.Y

As soon as a can is brought to the' saws4 by the feed-wheel and the latter has become. locked by the spring-pin 24 the levers 54 and are raised to release the sleeve 30 and connected with the loose gear by'means of a rod 63, having at its upper end a pin 64, whichy extends through the slots 62 in said levers, and at its lower end a pin 65,`whi'ch is engaged by a cam 66 upon one of the shafts 15 or 16, as the case may be. Thisrod has a longie tudinal slot 67 in its lower end, through which the lshaft extends, and this slot is of sufficient length to permit the required movement of the rod. As soon as a can-body is brought to the saws and the feed-wheel locked the rod 63 is moved downward by the engage-I ment of the cam 66 with the pin 65 and the sleeve carrying the saw is clutched for a short space of time to the loose gear 47 and the saw makes its orbital movement while the feedates the Jfeed-Wheel is making its return movement. vAs soon as the cam 66 has passed the pin 65 the spring 62 forcesA the outer ends of the `levers 54 and 55 downward and raises the rod 63. The c'am 52 upon the lever 54 then rides in the bottom of the groove 49b vand the spring locking-pin 56 the sleeve has completed its revolution, when the clutch-pin 49 is withdrawn by the cam 52 and the spring locking-pin 56 drops into the depression 57 in the collar 3C; and locks the sleeve until another can is brought into position and the rod 63 again tripped y,by the cam 66 acting upon the pin 65.

As the feed-wheel shown inthe drawings moved throughone-eighth of a revolution at each operation of the moving pawl 13, which As the shafts 15l and 1.6 rotate in unison, the sleeves carrying the sawfn'iechanism are operatively connected with the loose'gears 47 simultaneously eight times during the revolution of thev feed-wheel by the engagement the pins 6.5 upon the rods 63. i

The operator stands at the front ofthe machine and as each clamp rises above the bed ends of the can projecting beyond the ends of the clamp. Eachclamp has upon its loose clamp reaches its vertical position engages the inner or lower face of an arcuate guide 7] arranged concentric with the feed-wheel shaft 4. This guide bears upon the rollers 70 ofthe clamps or holders and presses the loose jaws firmly around the cans. end 71a vof this guide is inclined or turned slightly vupward so as to afford a cam-surface which wi l press the loose jaws of the holders upon the can-bodies. The guide 71, as shown, is

the cans have been removed by the saws the cans will be securely held within the holders chine, When'the ro'llers .will pass beyond' the lower end 71b of the guide. Y When the roller wheel isl stationary and the pawl which oper-r is operated bythe cam. 14 upon the shaft 15.-

ofthe cams 66 upon the shafts v15and 16 with of the machine a can is inserted within it, the.

The forward nearly simicircular, so that after t-he heads ofuntil-theyreach the lower part of the .ma--

rides upon the periphery of the collar 33 until i carries eight can-clamping devices, it is IOO jaw 8a a roller 70, which justbeforethe i properly engage the rollers and of a holder passes from the lower end of the guide, the hinged jaw of, the holder drops away from the can by gravity and the can falls out .onto the floorA or receptacle or any suitable conveyer for removing the'headless cans.,

As the cans which have contained food Istuffs generally have some remnantsof their former contents adhering to their inner Walls, I provide means for cleaning the interiors of the cans. during' the 'intervals occurring While the@ feed-Wheel is stoppedand the saws are making their orbital movement. For this purpose I provide a brush 72, ,4, which is 'mounted upon a spindle 73, Figs. 2, 3, and 4, the latter being journaled in a cross-head 74,

movable in a ideway 75. Spindle73 i's arran ed'at rigil; -angles to theplane of the fee -wheel and in such pc'isitionthat it willI when'moved longitudinally pass diametric .ally into the `interior of each holder `in-su`cces sion as the latter carrying the headlessgfcans 4come to a .position of rest opposite the fb'rush,

, This cleaning operation takes place While the holders are closed firmly upon the cans ,by theressure ofthe curve'd guide 71. brus -spindle 7 3 is'ra'pidly rotated by'means of a belt driven from any suitable power and Vapplied to a Wide flange-pulley 76'up'on the spindle, The brush-spindle is given al quick reciprocatin movement 'by means 'of. a cam 7 7, mounte upon the shaft 15,-which camz engages aroller 7 8 upon a lever 79, pivoted -at havin its flower end to a suitable su port" 8O and at its upper end abovethe cam avertical s 'ot 81, which is enga ed by a pin '82, secured a fork 73a, attac ed `to-'the crosshead 74. The brush-spindle is normally drawn in the direction 'efthe feed-wheel yby a spring 83, connected to the upl er end of thel lever 79 and to a fixed part o the machine.

The greater portion of the periphery of the cam-wheel 77 is concentric with the shaft 15,

to which it is secured. At one art of its periphe'ry the cam has a rather a rupt depression 77, which permits the lever 79 to be V drawn over toward the feed-wheel by the is mounted upon 'the shaft 15, a reciprocating movement will be given to the brush eight times d urin each revolution of the feedwheel, and t e depression 7 7-ain the cam 77 is so located as -to give this back-and-forth movement of the brush-s indle dur-ing the intervals while the feedeel is stationary.

While the roller 78 is riding u on the concentric or circular portion o t e cam 77 the seance brush-spindle Will of course have no longitudinal movement.

'In the drawings the parts yare shown in the position where the heads of a can-body havel just been cut off and the feed-Wheel is about to be moved by the feed-pawl 13. The sleeves carrying the saws are locked in their normal position. The saws, as has been stated, are constantly driven at a high rate of speed. The next operation Which takes place is the movement of the feed-wheel ythrough one-eighth of a revolution by the downward j movement of the feed-pawl. This brings a n'ew can-body to the saws, and the latter make incisions in the can-body be- `fre'the feed-Wheel comes to a complete stop.

As soon as the feed-wheel is stopped it is the-constantlysion ofthe rods 63, which are tripped by the Theserods release the locking and algain set them into positionfor stop ing the 's eeves afterthe saws have rotated a out the locked against further movement,vand the l .sleeves carrying the saws are connected to riveli gears 4.7 by the deprescan-body.l While this orbital movement of ythe saws is taking place and the feed-wheel is locked' the roller, upon the lever 79 enters and leaves the depression in the cam 77, and

a headless can is cleaned by the rotating brushfupon the 4spindle connected with the lever 79.' These operations ltake place dur theupward movement of the feed-pawl 1'32and are completed before the pawl unlocks the'feed-wheel and starts on'its downward theholdersW-hen the latter reach the of the curved guide.

The machine is automatic in its action throughout, and with an expert operator Who can place the cans in the holders as fast as the feed-wheel is operated it is unnecessary-to stop the machine. I provide means,

ttoln maystart the machine after a can'is placed in a holder and automatic means for stopping the machine'after the feed-wheel has moved forward one step and said can has been oper- For this purpose the worrn-wheel 20 is mounted loosely'on the is secured to said shaft adjacent to the Wormwheel, and these wheels, which serve as the opposing members of a clutch, are normally connected, so as to cause the rotation of the shaft by a spring-pin 86, arranged transversely ofthe wheel 'er member 85 and engaging'a notch in the worm-wheel. The member 85 has a peripheral groove 87, and the pin- Which extends across the groove has a vslot 88 cut 1n its sld e, forming a shoulder` S9, which is engaged at the complet-ion of each revolu- IOO The headless cans drop from however, whereby a jless' expert operator IIO `shaft 16 and a wheel 85, Figs. 2, 3, 7, and 8,

The arm 92 is connected by a link 95 to a treadle 96, and the latter is pivoted at its rear end to a fixture 97 upon the floor. The treadle -is supported normally by a spring 98, so that the shoe 90 is held Within the groove in the wheel 85. When the shoe is thus held within the groove, it Will be evident that the clutch-,pin will be disenga ed at the completion of each revolution and t at the machine will stop until the shoe is moved out of the groove by the depression of. the

` treadle. An operator Who is not expert,

therefore, after placing a can Within a holder depresses and immediately releases the treadle, and the .machine goes through one series of operations and thencomes to a stop automatically. When an expert operator is handling the machine,the tread 1e is kept permanently depressed by the foot or any suitable means and the machine runs constantly.

The complete loperation of the machine Will be. readily understood from the foregoing without further description.

While the ordinary toothed circular saws are found most suitable for use in connection with my machine, any other circular sawing devices suitable for the purpose, either yvith or Without teeth, may be used, and I do not wish to confine my claims to any particular kind 'of circular saw.
